According to distributive law,
 
A(B+C)=AB+BC,
 
So we simplify it as 4/5*6/5 +4/5*4/6,
 
As we know for multiplication we just need to multiply numerator with numerator and denominator with denominator, so the required result will be,
 
4*6/5*5 + 4*4/5*6,
 
24/25 +16/30,
 
Now, for addition as we are seeing numerator of both the numbers is not equal so we just need to take the LCM for equalizing the denominator. LCM of 25,30 will be the least number, multiple of both 25 and 30 that number is 150 or we can also apply the method in which we multiply the denominator  of  second number to first one and denominator of 1st to second one.
 
So required result will be:
 
24*6+16*5/150,
 
144+80/150,
 
224/150,
 
It can be also simplified as 112/75.
